Quotes from H. Martin

It will be seen that the Infinitive is a kind of noun with certain features of the verb, especially that of taking an object (when the verb is Transitive) and adverbial qualifiers. In short, the Infinitive is a Verb-Noun.

Since the Object of a verb in the active voice becomes the Subject of the passive form, it follows that only Transitive Verbs can be used in the Passive Voice, because an Intransitive Verb has no Object.
